To all whom t may concern.'

Be it known that I, GUsTAv R. Siam.- srRoM, a citizen of the UnitedStates, resid-V ing at Sheridan, in the county of Sheridan, State of Wyoming, have invented certain new and useful Improvements in Vehicle Springs; and I do hereby declare the ollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useiul improvements in springs and particularly to vehicle springs. y One object of the invention is toprovide a spring of this character which is arranged to sustain heavy or light loads with equal facility, and wherein the rebound willnot` damage the spring.

Another object is to provide a spring Vof this character wherein a` portion of the spring is adapted to yield under pressure of a light load without affecting the remainder of thespring, and wherein the light load portion will readily yield before the heavy load `portion comes into play.

Other objects and advantages will be ap` parent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is an elevation of a vehicle spring made in accordance with the present invention.

Figure 2 is atop plan view of the same.

Figure 3 is a vertical transverse sectional view on the line 3-3 of Figure 2, showing the clips in elevation. I

Referring particularly to the accompanying drawing, 10 represents a portion of a front axle, to which `the spring is arranged to be secured. The main portion of the Y spring, as shown at 11, consists of a plurality of layers, the central portion ofthe uppermost of which has the opposite lateral lugs or ears 12, extending therefrom, and on each side of these ears is a U-clip which, as shown at 13, embraces the layers of the spring and have their legs disposed through openings in the flanges of the axle. By this arrangement the ordinary method of passing a bolt through the centers of the layers, with the consequent weakening of the spring, is obviated. y

Secured to the outer ends of the uppervauxiliary springs and eXtendin i922.''rse-rialno,$77,675;S y v y most .layer of the main spring 11, are the auxiliary, or light load springs 14. Each of these springsr14 has its stem secured to y the main spring by means ,of the clips 15, the remaining portion of the spring eXtend-` ing longitudinally away from the main spring and having its end bent upwardly' and inwardly, as at 16, and being pivotally connected with the upper end of one of the shackles 17 and 17, which is engaged with the end of the main spring. The lower end of the shackle 17 is pivotally Vsuspended from the chassis 10 is pivotally connected to the front end of the horn 12. The auxiliary spring 14 is preferablyV formed in layers, with the inner layer 14', terminating a short distance from the end of the outer layer, and secured to the said outer layer bymeans` of the clip 18.

The force of a lightrload will cause the springs 14 to main spring, but when a heavy load is ap' plied, the springs'14will yield until they touch the ends of the heavyspring, when and yextended upwardly and inwardly over i the main spring ends, and shackles connecting the upwardly and inwardly extend-V ing ends of theauxiliary springs and sup. ,Y .portingly engaged beneath the ends of Ythe main sprlng.
